Good afternoon, John,

Thank you for contacting Mearto with your appraisal inquiry.
It would have been unusual for one set to include two sugar bowls and two cream pitchers so I am concluding that these are two sets that have been combined into one large set. Yoshino China is not as popular on the market as Noritake or Satsuma and, as a consequence, does not sell for very much and/or there relatively few auction records of sets selling, likely because they do not bring much money at auction.

Recent sales of Yoshino china are as follows, to give you a sense of the auction market:

Based on the photographs and information you provided, and subject to examination, you have:

possibly two sets assembled, comprising:
12 cups, 12 saucers, 12 side plates, 2 sandwich plates, 2 sugar bowls, 2 milk jugs.

&100-150 (represents a fair market value for auction purposes; retail or asking price may vary).
